About Colocasia 'Mojito'
Colocasia esculenta 'Mojito' · also called Mojito Elephant Ear, Variegated Elephant Ear · tropical
Colocasia 'Mojito' is a dramatic variegated elephant ear with huge green leaves splashed and streaked in near-black purple. This fast-growing tropical wants warmth, bright light, and constantly moist, rich soil. The ASPCA lists Colocasia esculenta as toxic to cats, dogs, and horses, so keep it well away from curious pets.
Ideal humidity: 60% or higher
Watch for — Leaf-edge browning and crisping: Usually low humidity or soil drying out. Raise humidity and keep the soil consistently moist; this is a water-loving bog plant.
The watering schedule, season by season
Colocasia 'Mojito' is a bog plant adapted to nutrient-poor wet ground — it must sit in a tray of pure water and must never get tap water or fertiliser. The base rhythm for colocasia 'mojito' is keep soil consistently moist; often 2-3+ times per week in active growth, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.
- Spring & summer (active growth): Spring and summer: keep the pot standing in 1-2 cm of distilled or rainwater at all times; top the tray up as it is taken up.
- Autumn (slowing down): Autumn: lower the tray water level as growth slows and (for temperate species) dormancy approaches.
- Winter (rest / dormancy): Winter: keep just damp, not flooded — many temperate carnivores need a cool dormancy with far less water.
This is a bog-margin plant that loves water. Never let the soil dry out during the growing season; it can even sit in a few inches of standing water. Reduce watering in winter when growth slows, but keep the rootball from drying completely.

How to tell colocasia 'mojito' needs water
A calendar is the worst way to water colocasia 'mojito'. Check the plant and the soil instead — for this species, look for these signals in order:
- The tray has run dry (during active growth it should rarely be empty).
- The peat-based medium feels dry rather than wet.
- Traps or pitchers shrivel or fail to form.
The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering colocasia 'mojito' for a day is almost always safer than over-watering it.
Overwatering vs underwatering colocasia 'mojito'
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For colocasia 'mojito' specifically:
Signs you are overwatering
- Blackening traps or pitchers from stagnant, warm, mineral-laden water.
- Rotting crown if kept warm and flooded through winter dormancy.
Signs you are underwatering
- Traps go limp and brown; pitchers dry up.
- The medium dries out and the plant collapses quickly.
Tap or bottled mineral water kills colocasia 'mojito'. Its roots cannot handle dissolved minerals — only rain, distilled, or reverse-osmosis water will do.
Water quality notes
Only rainwater, distilled or reverse-osmosis water — never tap, mineral or softened water. This is the single most important rule for colocasia 'mojito'.
Seasonal and environmental adjusters
Every figure above shifts with the conditions in your home. For colocasia 'mojito', the levers that matter most are:
- Bright light plus the water tray is the whole game — no fertiliser ever goes in the soil.
- In hot weather the tray empties fast; check it daily.
- Temperate species need a cooler, drier winter dormancy, not constant flooding.
Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of colocasia 'mojito'.
